"It may be a little jarring at first -- in our fat-hating culture it can be more shocking to hear someone use the word 'fat' than it is to hear them drop the other f-bomb. But both words are perfectly useful Anglo-Saxon monosyllables.
Fat is just a word, and a simple, accurate word at that. Unlike 'overweight,' it doesn't imply that there is only one weight that is right. Unlike 'obesity,' it isn't a medical term with particular implications about illness and disease.
'Fat' is just fat, like 'bald' is bald, 'short' is short, and 'green eyed' is green eyed. It just is what it is. And that's okay."
